Paper Abstract

Space-time coding based on transmit diversity have recently proposed as a design art of signals for transmit diversity in satellite-data communications. The paper mainly discusses the performance of some STCs applied to the forward link of a WCDMA multi-satellite UMTS environment. MRC, STBC, SDT and STTC have been firstly considered. Furthermore, outer convolutional encoder have been considered to concatenate with MRC, STBC and STD, while for STTC, a convolutional encoder plus an iterative decoding has been used to perform a STTCM. Simulation results show that STD outperforms all the other schemes in terms of BER and FER for lower values of SNR. While the SNR is increasing, STTC and STTCM have shown the best performances in terms of FER. Performance results with various modulation methods for the serially concatenated convolutional STBC system are also presented here.
